Setup SQL Server for CLR Procedures

NCache provides you with CLR stored procedures that synchronize the cache with the database. It does not involve database monitoring or a notification mechanism, instead, the user can execute any complex logic using CLR procedures, and saves the user with too many notifications being thrown.

Follow the given steps on the database in order to enable CLR procedures and then implement them.

How to Setup SQL Server for CLR Procedures

In order to use CLR stored procedures, make sure that CLR integration is enabled on the database. If you haven't enabled CLR integrations already, then execute the following command to enable CLR integrations:

-- Enable CLR Integration on Database
sp_configure 'clr enabled', 1
GO
RECONFIGURE
GO

Step 1: Enable CLR on Database

To use NCache in the CLR stored procedure, NCache assemblies need to be registered with the database. This will enable the database to use NCache API in stored procedures. NCache provides CLRStoredProcedure.NCache for the required dependent assemblies. Therefore, you first need to download the CLRStoredProcedure.NCache NuGet package or install it in your application. The required assemblies should be referred from this NuGet package.

Step 2: Install NuGet Package for Assemblies

Once you have the NuGet package, deploy the assemblies using the following commands:

Note

In order to deploy Alachisoft.NCache.Client.dll in the following query, you need to provide the path according to the location of the NuGet package.

USE Northwind
ALTER DATABASE Northwind
SET TRUSTWORTHY ON;
GO
-- REGISTER SYSTEM ASSEMBLIES ...
DROP ASSEMBLY [System.Web]
DROP ASSEMBLY [System.Management]
DROP ASSEMBLY [Microsoft.CSharp]


CREATE ASSEMBLY [System.Web] FROM N'C:\Windows\Microsoft.Net\Framework64\v4.0.30319\System.Web.dll' WITH PERMISSION_SET=UNSAFE

CREATE ASSEMBLY [System.Management] FROM N'C:\Windows\Microsoft.NET\Framework64\v4.0.30319\System.Management.dll' WITH PERMISSION_SET=UNSAFE

CREATE ASSEMBLY [Microsoft.CSharp] FROM N'C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Microsoft.CSharp.dll' WITH PERMISSION_SET=UNSAFE

CREATE ASSEMBLY [Alachisoft.NCache.Client] FROM N'C:\Users\john_doe\Downloads\CLRStoredProcedure.NCache\lib\net40\Alachisoft.NCache.Client.dll' WITH PERMISSION_SET=UNSAFE

After following these steps, the environment for CLR procedures will be set. Please refer to Programmer's Guide to get help in the implementation of stored procedures.

Step 3: Deploy the Assemblies
